This is the third video in a four-part series which describes taking photographs through a telescope using a DSLR camera.
This specific video concerns how to determine approximate exposure times for various types of mounts, including manual mounts, alt-az tracking mounts, and equatorial tracking mounts.
The need for the longest possible exposure times is emphasized when taking photographs of deep sky objects (DSOs).
The technique of using image integration - or image stacking - is discussed, and sample photographs are included to show the effect of image stacking on the quality of images.
Encouragement is offered to those who might feel intimidated by the notion of taking pictures through a telescope, especially with regard to learning image integration or image stacking techniques.
Introductory and closing music is "So My Love - Instrumental Version" by Anthem of Rain:
